Romney Stumps With Rubio: Ticket-Testing?

One day Romney and Rubio are campaigning together in Pennsylvania; two days later, Rubio is giving what is being called “a major speech” on foreign policy. Auditions?

Just as he did while campaigning with Rep. Paul Ryan in Wisconsin and other big names — Ohio Sen. Rob Portman, Virginia Gov. Bob McDonnell, South Carolina Gov. Nikki Haley and New Hampshire Sen. Kelly Ayotte — Romney didn’t indulge in veep speculation in his first press conference in over a month.
